Save $2,300 off the 13.5 kW Tesla Powerwall.

Plus sign up to the Origin Loop virtual power plant (VPP) and stay connected for five years to save a further $1,500.

You may choose whichever Origin Energy plan you like, however, the 14c FIT is only applicable to Solar Boost Plus plans.

Interested in everyone's thoughts around VPP and if the discount is worth the intermittent power drain.

Interest free plans available.

Not available in all areas. Price for a standard installation within 50 km of the Sydney, Melbourne, Brisbane, Wollongong and Gold Coast CBDs.

Mod 26/7: Edited title. The $1500 off after 5 years is included in the $13,995 price (thus why it says 'from $13,995'), it is $15,495 initially ($2,300 off).

                      @1st-Amendment: The investment will pay off over time, the price of electricty isn't going to get any better any time soon. So paying for the infrastructure to generate your own electric is a good idea it will save you money over time, there are people here in queensland and consitantly get 0 dollar bills with setups like this or better. It pays for itself, the more people buy ev;s the more demand on the grid the higher the prices. Thats why a setup like this is a good idea for every home.

                        The measure of a good investment is how it compares to other ways you could spend your money. Spending $28k to save a few hundred dollars in 15 years time is a terrible investment

                          @1st-Amendment: if you spend less than 0 every year on electric and in some cases even make money from the electrical companies because you generated too much electricity and are able to sell some back, how much do you think that is over 15 years? average bill for people ranages from 400 to 600 per quarter depending on how many people live in the place, some even higher this is with out any kind of solar to offset. Say its the 400 a quarter over 15 years thats, $24000 saved or if you are able to generate and sell back excess electric that could be 28k or more over those 15 years. Also I don't know many people that stay in a house for that long, if you make a profit on a house sale you get that 28k back you spent, and if anyone has it the investment and cost of it is less and less. Your not seeing the big picture here.

                            Someone else already posted a better investment option. Put $28k in your offset account and will return $68k over 15 years.

                              @1st-Amendment: I based it on a 400 dollar a quater figure this would be in a perfect world no one has the exact same bill every single quarter it varies I was just giving you an example but in realitiy that figure could be much higher, but if you continually get a 0 or less bill then forcasting this is hard. Thats all this is a forcasted figure, that could or not happen I was trying to fit your example into workable numbers. None of these figures are set in stone, they were just to try and give you context of what could happen over time. if you were to have a 0 dollar electric bill over 15 years or more. Yep the other guy explains it better than I ever could I probability should have just quoted that guy.

                                  @1st-Amendment: I'm interested in you thinking here. Perhaps you don't have the best plan for your powerwall? I have a time of use plan input into the tesla app, and I'm using the AGL solar EV night saver plan which has 8c electricity between midnight and 6am. I charge my batteries for the car and the house overnight. This covers the electricity use in the morning when we all get ready. The batteries recharge from solar typically before 11am on a sunny day. then its all Feed in. The batteries cover the use in the evening. they then charge again at 8c. So i'm essentially paying 8c for my electricity use and selling the solar back during the day. 2xPowerwall 2, price was locked in at 10k each. This setup was implemented last month. Tesla App "impact" shows the savings based on the energy used, times, feed back, and battery use. So middle of winter it saved me $220 that month. The lowest solar, highest heating/energy use produced a saving of over $200 for that month. I'll be very interested to see how this performs over a 12 month period, but having batteries that return energy bought at 8cents replacing the off peak and peak costs of use, and selling solar during the day seems like a very effective use of batteries.

                                  Maybe its your setup and plan that makes it a poor investment?

                                    Your situation appears to be based on a purchase price which is not available to anyone else.

                                    @$15k per PW2 you're talking $30k outlay on day one for 2 PW's. I've lived in my house for 20 years and still haven't used $30k worth of electricity (I keep records), so it's not economic for me at these prices. If I put $30k into an index fund @8% return for 20 years it'd be worth $147k. That seems like a much better investment to me than paying $30k for possibly $30k of electricity.

                                    Maybe its your setup and plan that makes it a poor investment?

                                    See above. There's much better returns to be had on your money than a home battery.

                                    and selling solar during the day seems like a very effective use of batteries.

                                    While FITs exist, but they will be going away soon as supply far outstrips demand.

                      @1st-Amendment: $14k kept in offset account for 6% interest rate home loan would save $54k in interest over the life of the loan (30 years), and you would still have $14k saved up in your offset account.

                    @kungfuman: Is it legal to go off grid and have a generator if I can't get enough panels and batteries?

                    I was reading that there is an attitude that the poor without solar panels are paying for the grid, and the rich exporting power aren't contributing. They reckon the solution is to pay electricity subsidies, but I reckon they'll ended up bumping up the daily connection fee.
                    There was also talk on making solar panels compulsory on rental properties.

                    I was hoping they'd do another subsidy on getting panels, and hopefully batteries.

Which is free electric. I don’t know why this is the issue? Unless your bill for electric is less than 400 a quarter then I understand why this doesn’t work for u but for alot of people this is a good return over time.

                        @kungfuman: Have you accounted for the decrease in battery capacity and battery health over time? The battery will still work in 15 years, sure, but it isn't going to be performing anywhere near as well as it was in year 5 or even year 10.

                        Basically with battery storage at the moment it seems that it will pay itself off it it works at 100% optimum conditions all year round (which it won't) for 10+ years (which it won't). As someone else said, as an investment it's a terrible idea. You will get far better returns on even putting it in a high savings bank account.

                        I'd love to get this deal, but it maybe paying itself off in 15 years isn't filling me with confidence. Within 15 years I'm hoping we'll have a nuclear power plant in Australia to solve all of our energy issues anyway.

                        @kungfuman: The issue is you clearly don’t understand the word “free”. Spending money to get $0 bills doesn’t make it free electricity.

                        People have clearly pointed out the opportunity cost makes this a terrible decision, unless seeing $0 on your electricity bill is all you want in life. The reality is most people would be a lot better off investing it, even with your $400 a month bill. That it might pay for itself over 15 years is not a good investment. Or even over 5 years - not when $27k can earn $1,200 a year.

                        Best option for near everyone is wait until electricity prices are higher and battery prices are cheaper. With V2H cars coming, likely one of those will make even more sense.

                      @Poor Ass: Worth running your own numbers but a battery at their current prices is a terrible idea if you're looking to save money. Even in an ideal case where you fully discharge it every night and fully charge it during the day using excess solar energy you can't sell back to the grid as your feed in is capped you're lucky to break even in 10 years. After those 10 years or typically 3650 cycles your warranty is worthless and your battery won't last much longer than that, but with winter existing there's no chance your battery is ever going to see a perfect life for profitability. They may be running ads with astute looking people talking about the merits of a home battery but in reality you're spending a heap of money on an investment you'll be lucky to see any return on over a long period of time.

                      I wouldn't expect prices to come down for a long time either, EV demand is sure to keep lithium in high demand and prices need to drop a long long way to become worthwhile.

                @kungfuman: I could get close with one, if I upgraded my insulation and went to a temperature where I had to wear a jumper inside. But by then I'd have spent $75k on avoiding my power bills, which after the solar ($10k) is about $1000 a year. Also my wife would probably die or leave me, since she is already wearing a full warm tracksuit and uses a blanket, laying under the heater (set to 24) shivering. Although I don't think the heater is working fully, the other living area which is set to 18 is warmer, think the temp sensor in the lounge is at fault though.

                Stupid massive windows giving great natural light and views. The living rooms each have 2 1.8x2.5m and 1 1.8x5m. The dining room and laundry have big glass sliding doors with a glass panel. The master bed has a 1.8x4m window and the others all have 1.5x2m windows at least at guestimates because I can't remember the exact figures I sent in for a quote.

                Buying curtain bots and presence sensor to automatically close and open the thermal curtains would probably be a better return on investment. I've seriously considered it, since I seem to be in a never ending battle of closing them because other people like the sun, but don't close curtains when they leave the room.

                Inside is currently 22 degrees, between the curtains and the glass is 10 and outside is 1. If the curtain is open you can feel the heat being stripped out of you from over a metre back. After the ac goes off at 11pm the internal reading will drop to 13, 3 between the curtain and -2 outside by around 5am.

                Roof is apparently decent insulation, but I've thought of improving it, underfloor and wall is non-existent, floor might be worth a self install, but walls are pointless with the windows.

                  @johndoh89: Thanks for the write-up!
                  I'm in a similar situation with similar single glazed walls. We have the split system in the livingroom and master bedroom (simple heater in the kids room).
                  The problem with the ac in the bedroom is the air gets very dry. Humidity in the house is below 25%. Around 20% in the bedroom if ac running but could be lower, I think 20 is the lower end of what the senso shows. -quite uncomfortable. I now have a small humidifier, it gets the Humidity up to 35-40%. And we also dry our laundry inside to keep the Humidity up.

                  The plan is to change windows to double glazed, (maybe triple but then the paper walls would be the absolute weakpoint) but the energy prices are not qute there yet to justify the reno.
                  Imho, ppl complain about the energy prices, but energy is still relatively cheap in Australia. Takes a bit more for the big country-wide insulation reno boom to start.

              What's worse about that 25% is it's the different between me paying 0 dollars a year and probably now paying close to 300.. I really like not getting bills with my modest solar array.

        I think Powerball battery can only store 13.5kw max if I remember correctly and you need to have a min 6KW+ unit to has this installed. 14c is not locked for a year or 2 and they can change anytime after that so expect 5c-8c afterwards. if you are using 20kw a day for 350 days @ 30c/kw then $2100 + daily charge a year, if you can store 10Kw everyday (depends which state you live as well) , then your saving would be 10kw x 350 days x 30c/kw = $1050. You will need 12+ years to get your money back assuming electricity price remains unchanged (impossible) and you battery/solar panel/inverter will last beyond 10 years without losing any efficiency.

                @zerog101: I've got a grid connect battery. Any reason you don't charge during off-peak/shoulder on cloudy days?

                If you've got flat rate then it wouldn't make sense but for me with a 20c difference between shoulder and peak if I charge to 60% it usually takes a good chunk off my peak. Although the battery is much smaller at 5kWh

          There is another variable that makes the ROI on batteries more attractive: when you join a VPP your energy prices will be significantly cheaper off-peak and that is when you will use the grid, if ever, due to load optimization. So not only will you consume less energy from the grid, your energy prices will be much cheaper when you do use the grid.

          • JCRALLYART on 25/07/2023 - 09:34

            @biogenesis: Unless you have a full electric car to charge, otherwise to get 10kw stored in the battery everyday means you will have to switch on all the electrical appliances to use up all the energy stored.

              It was undoubtably a dumb promise to make. Nonetheless, the LNP line that you are either falling for, or spinning, which is that Labor promised price reductions immediately, is the real lie.

          You need a very specific usage pattern to take advantage of a battery, basically low daytime usage and highish night time usage. You might have a bright sunny day to charge the battery but if you go out for the night then you won't use the power. If you go on holidays for 10% of the year that's 10% less you'll use the battery. Then there's days when you use all the power during the day, like hot overcast days on the weekend running the aircon. End of the day thinking you'll charge and discharge 10kW every day is a false narrative. It would lucky to end up being 60% of the time.

                @amsaini15: That's exactly the same one as what Origin is advertising, Tesla PW II 13.5kw. In summer, we can run our two split systems (both over 7kw) until we feel cold, and it still have reserve to cover idle appliances. Note that this will depend on your solar panel orientation - ideally you should have some panels to the west. Winter is a bit meh in Melbourne.

                Can't tell you the cost as my builder bundled it in the building price. Like I said, back then the ROI wasn't good but not having to pay a cent during summer is a winner. Also at a pitch-dark night during a blackout, seeing only my house standing proudly brightly lit is quite a feeling haha. All in all I find it quite valuable, but everyone is different.

            @NuttyGoodness: Longer than that. I've had some lithium battery solar storage for 4 years and the capacity is 99% of what it was when installed. The expected lifetime is around 25 years to 80% capacity. The batteries have improved a lot and solar storage is a low intensity use case so isn't very hard on the cells.

              @Dsiee: Some of those tests are done under laboratory conditions. They don't translate well to real-world conditions. With that said, you can always setup the system to be used and have low deterioration.

              I am all for Home Batteries. If not all, but a majority of homes had a battery, and not a large unit but a decent sized one… that would go a LONG way to balance the grid. We could actually make the system more efficient, and be more resilient in times of storms/blackouts. Australia's network generally doesn't need it, since most of the populous are concentrated in major towns and cities.

              Personally?
              I would like to own my own home, have my own solar system, have my own battery, have an electric car, and regulate my household energy. I think I could find a better balance of using the car and battery to store excess power, giving back to the grid during demand on-peak, and taking out from the grid during slow off-peak times. It would help balance the grid, generate income, reduce expenses, and do it all with renewable energy source. If it pays for itself off in 5 years great, if it takes 20 years also great…. I just don't like being at the whims of the Big Oil Tycoons, especially after their shenanigans in 2022, with more to likely come in the future.
